Description

Description Rubber-like elastic parts Technical field

TECHNICAL FIELD The present invention relates to a rubber-like elastic component which is used between two members facing each other without using an adhesive. The rubber-like elastic component of the present invention is used, for example, as a gasket for sealing between two members, or as a damping rubber for suppressing propagation of vibration between the two members. The rubber-like elastic part of the present invention is also used as a rubber-like elastic part for a hard disk drive (HDD), for example, as a connector gasket for HDD or a voice coil motor (VCM) damper for HDD. Background art

For example, in HDDs, gaskets made of an elastic material such as rubber or resin are attached to the top cover (lid) and the connector connection, respectively, to prevent foreign matter such as dust and moisture from entering the HDD. I have.

Of these, the connector gasket to be attached to the connector connection part is often a single piece of rubber and has a flat shape.In addition, both sides have a reduced contact area in consideration of the gasket's adhesiveness. Rip-shaped ones are used.

This connector gasket is used to seal the portion where the signal from the head is taken out of the HDD enclosure via the flexible circuit (FPC), and is usually mounted around the connector mounted on the FPC, and the FPC and aluminum Die-casting + It is sandwiched between the bases of the cationic coating, and exerts a sealing effect by being tightened with screws.

FIG. 20 shows an example of this, in which the FPC 52 is attached at a predetermined position inside the base 51, and this FPC 52 is removed from the base 51 and turned upside down as shown in FIG. Have been. In FIG. 21, reference numeral 53 denotes the center of the plane of the FPC 52. A connector gasket 54 that seals between the base 51 and the FPC 52 is attached around the connector 53. By the way, during the manufacturing process of HDDs, after assembling, the HDDs are operated and inspections are performed, and as a result, rework is frequently performed. However, workability during rework is particularly important.

However, conventionally, since the gasket 54 adheres to the base 51 and the FPC 52 due to the adhesiveness of the gasket 54, the once mounted FPC 52 cannot be easily removed from the base 51. Deterioration of workability is a problem. This is because the gasket 54 sticks to the mating member (the base 51 and the FPC 52) due to the temperature rise accompanying the operation of the HDD.

Furthermore, when the base 51 and the FPC 52 are removed, it is not fixed whether the gasket 54 adheres to the base 51 or the FPC 52 side. The work procedure at the time cannot be fixed. In particular, if it has adhered to the FPC 52 side, when attaching the FPC 52 to the base 51 again, peel off the gasket 54 from the base 51 force each time and attach it to the FPC 52 side. I also have to do the work. Accordingly, it is necessary to check whether the gasket 54 is attached to the FPC 52 or the base 51 for all of the reworked parts. In order to attach the gasket 54 to either the FPC 52 or the base 51 without fail, it is sufficient to attach the gasket 54 with adhesive on one side, but in the case of HDD, it is generated from the adhesive. Outgassing may cause malfunction.

In view of the above, the present invention provides a rubber-like elastic component that is sandwiched between two members facing each other without using an adhesive, and the rubber-like elastic component adheres to either of the two members.

Therefore, the gasket 1 is always separated from the base and adheres to the FPC side due to the magnitude of the adhesive force due to the magnitude of the contact width or the contact area of the contact surfaces 6 and 7. The ears 3 are provided as tabs for preventing the gasket 1 from being erroneously assembled. That is, a groove (recess) for mounting the connector is provided on the base, and when the gasket 1 is assembled with the connector in the groove, the ears 3 will interfere with the base. Since the assembly cannot be completed, it is possible to notify that the assembly is erroneous. The ears 3 are provided flush with the contact surface 7 on the FPC side of the gasket 1 as shown in FIG. 16 (B), but as shown in FIG. 5 (C), In the middle position in the height direction (left and right in the figure) 4 May be placed.

The ears 3 are also provided as tabs for easily separating the gasket 1 from the FPC. That is, as described above, when the FPC is removed from the base during rework, the gasket 1 must adhere to the FPC side for work, but the gasket 1 must be replaced due to a defect in the gasket 1 itself. Peeling off the gasket 1 from the FPC, if necessary, is another difficult task. The ears 3 are provided in order to easily peel off the gasket 1 in such a case. The provision of the part 17 facilitates the work when the gasket 1 is peeled off from the FPC side.
